The breathing check is done by checking for pupil dilation. checking for discoloration of the skin. looking, listening, and feeling for air exchange. checking the pulse.

i dont think this is the place to ask this.

maybe uh, try talking with someone you know or like about this.

life can be tough.

if your boyfriend is cheating on you, my best advice to you is to dump him, he's only going to drag you down. and if you do, don't fret there's plenty better that know how to treat a person right. i mean honestly, the whole point of a romantic relationship is love, and if you love someone you aren't going to cheat on them. i do believe in second chances, but why would he cheat in the first place? i personally feel that if someone cheats, they ruin any chance they wanted/had with you. i wish you the best of luck with this, hang in there.
